Lee and Oscar started jogging from the same point. Oscar started jogging 4 minutes earlier than Lee. Lee's jogging speed was 350 m/min and Oscar's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Lee to catch up with Oscar? 
2. What distance would Oscar have jogged when Lee caught up with him?  Express your answer in meters.

	Lee	Oscar
Speed	350 m/min	150 m/min
Start time		4 min earlier
Extra distance covered at first		600 m

(a)
Distance that Oscar covered when he jogged 4 minutes earlier
= 4 x 150
= 600 m

Distance that Lee covered more than Oscar per min
= 350 - 150
= 200 m

Time that Lee needed to take to cover the additional 600 m
= 600 ÷ 200
= 3 min

(b)
Time that Oscar would had jogged when Lee caught up with him
= 3 + 4
= 7 min

Distance that Oscar would have jogged when Lee caught up with him
= 7 x 150
= 1050 m

Answer(s): (a) 3 min; (b) 1050 m
